Engine Nerd

Hey everyone. I bought another G8! This time its a 2008 GT. I found it on FB. A small dealer bought it from an auction not running, engine half disassembled. He was going to sell it to a junk yard if no one took it because he doesn't have time for it, so I figured I try and save it from death. Not sure yet whats wrong with the engine and it needs some body parts (hood vent and spoiler cover). I bought it site unseen from TX, and I'm currently in AZ but the car is in CA where I normally live. (life in the military is trash, I'm never where I want to be) So the situation is kinda FUBAR. But, once I have the opportunity to get it running and driving again I plan to sell it back into the market; so someone else can enjoy it. I already have my 09 GT for a daily. Already bought a bunch of parts for it. Just wanted to document the process somewhere. I'm pretty excited to get this project going! :grin2: I'll make updates as progress is made. While I'm gone my friend is going to work on it and send photos for everyone to gander at.

That does sound like a real project, but with the potential to be rewarding. If you're on active duty, you may have access to an auto hobby shop for a place to work and tools you may not own. You probably know that.

In 1972, I was at the Fleet ASW School in San Diego north across the bay from North Island. I pulled the heads on my 1965 Le Mans and had them sent out for a valve job when I was there.

So, my buddy got to poking around the engine a little. Very quickly found the reason the car did not run. A rod appears to have tried to make window in the block. Not an ideal situation. I cant seem to find any L76 short blocks for sale near San Diego so it may end up getting a Camaro engine.... I'll keep looking for a L76 for a little while though.

Small update.... Purchased a new block from Summit Racing, and new bearings and rod plus other things for the engine rebuild. Around $1400 out the door for a bare aluminum block. 140 pounds the way it sits in the box. Pretty light. I'm still out of state from where the car is, so I only have the pictures my fiend gives me. But the engine rebuild should start this weekend. I'll keep updating as progress is made.

Things are getting spicy with this rebuild now. The piston has seen better days for sure, but it was expected. The head and valve on the other hand are perfectly fine dispite obvious contact with the piston at high speed. It will still need to be inspected for cracks though.

Tear down complete. A few more casualties to list. It jumped time slighty but no real damage; the crank has some debris damage but i think itll polish out. Time to take the rotating assembly to the machine shop to be cleaned and balanced for the new parts.

I havent been consistantly in the state for a while to update. But here it is. I decided to buy a new block from summit and build this engine up with forged internals. Eagle H beam rods, DSS pistons, BTR cam kit with titanium retainer, dual springs, ARP studs... the works.

We all know about the AC belt throwing, but has anyone here had their tensioner break? After my cam upgrade, my AC belt would throw pretty often, although then I noticed that my AC tensioner itself was actually broken. There was a piece of the metal that was missing and the tensioner wouldn't...

So, I'm persistently getting misfires on cylinder 6 which is #5 being 6th in the firing order. I've already ruled out the plug, plug wire and coil by way of swapping the coil and replacing all of the plugs and wires with brand new. I checked compression and compared with neighboring...

Hello fellow Pontiac g8 owners my name is dave and I own a 2009 g8gt that I bought new in 09. I had a ant infestation last summer that destroyed the hood insulation on the car. I would like to buy a factory replacement but I should be looking for unicorns instead! Has anybody possibly seen or...

New to the board and I should probably introduce myself. I am new to G8s, but not to LS vehicles. I have owned a couple fourth gen F-Bodies, had a 76mm/80E/Etc. 2003 Silverado. I have also started and sold quite a few turbo LS builds including a foxbody, S-10, Volvo 245 and probably some other...

Planning on getting the GXP rear diffuser and having seen a lot of other muscle cars out there with body colored diffusers, got me wanting to get mine painted. Anyone have any luck doing this and if so, how did it turn out?
